The influence of mesoscale eddies on the detection of quasi-zonal jets in the ocean

Creator:: Schlax, Michael G. and Chelton, Dudley B.
Abstract:: Westward propagating Gaussian eddies with statistical characteristics estimated from altimeter observations but with purely random starting locations and times produce striated features in time-averaged maps of zonal velocity. The striations in these simulations have magnitudes and meridional scales comparable to those reported from time-averaged altimeter observations and model output in...

Enhanced southward flow over the Oregon shelf in 2002: a conduit for subarctic water

Creator:: Kosro, P. Michael, 1951-
Abstract:: Moored current measurements from the Oregon shelf during 1998–2003 are used to estimate time series of anomalous alongshore currents and pseudo-displacements, after accounting for the mean and seasonal cycle. From early January through mid-June, 2002, currents at 10 m were anomalously strong toward the south by an average 12 cm/s,...

Global observations of large oceanic eddies

Creator:: Chelton, Dudley B., Schlax, Michael C., Samelson, Roger M., and de Szoeke, Roland A.
Abstract:: Ten years of sea-surface height (SSH) fields constructed from the merged TOPEX/Poseidon (T/P) and ERS-1/2 altimeter datasets are analyzed to investigate mesoscale variability in the global ocean. The higher resolution of the merged dataset reveals that more than 50% of the variability over much of the World Ocean is accounted...

Satellite Microwave SST Observations of Transequatorial Tropical Instability Waves

Creator:: Chelton, Dudley B., Wentz, Frank J., Genremann, Chelle L., de Szoeke, Roland A., and Schlax, Michael G.
Abstract:: Satellite measurements of sea-surface temperature (SST) by the TRMM Microwave Imager reveal previously unreported features of tropical instability waves (TIWs). In the Pacific, TIW-related variability is observed from the eastern boundary to at least 160°E. Cusp-shaped distortions of SST fronts and associated trains of anticyclonic vortices both north and south...

Feeding methane vents and gas hydrate deposits at south Hydrate Ridge

Creator:: Tréhu, Anne Martine, Flemings, Peter B., Bangs, Nathan Lawrence Bailey, Chevallier, Johanna, Gracia, Eulalia, Johnson, Joel E., Liu, C. S., Liu, Xiaoli, Riedel, Michael, and Torres, Marta E.
Abstract:: Log and core data document gas saturations as high as 90% in a coarse-grained turbidite sequence beneath the gas hydrate stability zone (GHSZ) at south Hydrate Ridge, in the Cascadia accretionary complex. The geometry of this gas-saturated bed is defined by a strong, negative-polarity reflection in 3D seismic data. Because...

Tracer-derived freshwater composition of the Siberian continental shelf and slope following the extreme Arctic summer of 2007

Creator:: Abrahamsen, E. Povl, Meredith, Michael P., Falkner, Kelly, Torres-Valdes, Sinhue, Leng, Melanie J., Alkire, Matthew B., Bacon, Sheldon, Laxon, Seymour W., Polyakov, Igor, and Ivanov, Vladimir
Abstract:: We investigate the freshwater composition of the shelf and slope of the Arctic Ocean north of the New Siberian Islands using geochemical tracer data (δ¹⁸O, Ba, and PO₄*) collected following the extreme summer of 2007. We find that the anomalous wind patterns that partly explained the sea ice minimum at...

Space-based lidar measurements of global ocean carbon stocks

Creator:: Behrenfeld, Michael J., Hu, Yongxiang, Hostetler, Chris A., Dall’Olmo, Giorgio, Rodier, Sharon D., Hair, John W., and Trepte, Charles R.
Abstract:: Global ocean phytoplankton biomass (C-phyto) and total particulate organic carbon (POC) stocks have largely been characterized from space using passive ocean color measurements. A space-based light detection and ranging (lidar) system can provide valuable complementary observations for C-phyto and POC assessments, with benefits including day-night sampling, observations through absorbing aerosols...

Aragonite saturation state dynamics in a coastal upwelling zone

Creator:: Harris, Katherine E., DeGrandpre, Michael D., and Hales, Burke
Abstract:: Abstract: Coastal upwelling zones may be at enhanced risk from ocean acidification as upwelling brings low aragonite saturation state (Ω[subscript Ar]) waters to the surface that are further suppressed by anthropogenic CO₂. Ω[subscript Ar] was calculated with pH, pCO₂, and salinity-derived alkalinity time series data from autonomous pH and pCO₂...

Oceanic phosphorus imbalance : magnitude of the mid-ocean ridge flank hydrothermal sink

Creator:: Wheat, C. Geoffrey, McManus, James, Mottl, Michael J., and Giambalvo, Emily
Abstract:: We present a new estimate for the crustal phosphorous sink that results from reactions among seawater, basalt, and sediment blanketing low temperature mid-ocean ridge flank hydrothermal systems. New estimates for global hydrothermal power output, sediment thickness, and the dissolved phosphate concentrations in basement formation fluids indicate that fluid flow through...

Possible emplacement of crustal rocks into the forearc mantle of the Cascadia Subduction Zone

Creator:: Calvert, Andrew J., Fisher, Michael A., Ramachandran, Kumar, and Tréhu, Anne Martine
Abstract:: Seismic reflection profiles shot across the Cascadia forearc show that a 5–15 km thick band of reflections, previously interpreted as a lower crustal shear zone above the subducting Juan de Fuca plate, extends into the upper mantle of the North American plate, reaching depths of at least 50 km. In...
